Currently replaying Pokémon X with a Mono Psychic Team. I have recently dealt with Team Flare at the Kalos Power Plant.
Current Team (In no particular order):
1. Harkanian the Slowbro
Ability: Oblivious
Moves: Surf, Confusion, Slack Off, Headbutt.
2. Simon the Sigilyph
Ability: Wonder Skin
Moves: Psybeam, Air Cutter, Synchronoise, Fly.
3. Jack the Gallade
Ability: Steadfast
Moves: Psycho Cut, Low Sweep, Rock Smash, Strength.
4. Ursula the Malamar
Ability: Contrary
Moves: Foul Play, Aerial Ace, Payback, Hypnosis.
5. Nick Wilde the Delphox
Ability: Blaze
Moves: Mystical Fire, Psyshock, Grass Knot, Cut.
6. Angry Sun the Solrock
Ability: Levitate
Moves: Rock Slide, Psychic, Fire Spin, Rock Polish.
I will be teaching broader moves to some of them the more I progress through the game.
To keep things as balanced and somewhat challenging as possible, I switch the Exp. Share on and off, generally reserving it for major boss fights.
